McAlpine water seal tubular trap features an adjustable inlet that makes the tool suitable for all domestic repair, maintenance and improvement work. The anti-syphon valve neutralizes syphonic pressure before it reaches the seal of the trap and therefore provides the equivalent of a ventilated system. It features a Silentrap that will not unseal under high pressure or abnormal conditions making it reliable and user-friendly.
